To all whom it may concern:.

-Be it known that I, Join; Srnnmi, of Adelphi Iron Works, Salford, inthe county of Lancaster, England, engineer, have invented new anduseful. Improvements in Apparatus for Drying Proofed and Like Fabrics orMaterials, of which the following is a specification.- This inventionrelates to apparatus for drying proofed and like fabrics or materials ofthe type in which the fabric is passed through a chamber containingheating and cooling elements for vaporizlng and condensing the volatilesolvents contained in the I 5 fabric, or in which the vapors arecollected for subsequent condensation in a separate condenser. With suchapparatus there is a tendencyfor a part of the. vaporized solventstoescape from the condensing or co l-' lecting chamber at the pointswhere the fabric or material enters and leaves the same,

due to disturbing air currents or drafts and to the motion of thefabric.

The object of my present invention is to v provide means for preventingthe aforesaid ofthe form shown in Fig. 2; Fig. 4 is a sec'tional-elevation taken on theli'ne AA. and looking from the leftto theright of Fig. 3; Fig. 5 is a sectional elevation taken on the line B -Bof Fig. 2, showing the jetproducing arrangement at one end-of the dry- 5ing chamber, certain 'partsbeing omitted fort-he sake of clearness;Figs.-6 and 7 are enlarged detailed views.-

The same reference characters indicate the same parts in the'difierentfigures. g In the apparatus illustrated in Fig. 1 I provide an outlet atthe upper end of the chamber aand connect the same to'the inlet,

n or suction pi e of a farn'or exhausterb, and

' I rovlde' a 'acent to the pointswhere the 5 fa ric entersandleaves-the'chainber, pipes 0, d each having a longitudinal slit a seriesof ports -therein, so arranged as to direct the air supplied to the pipeon to the fabric e as it enters'and leaves the chamber.

-The fabric is dried by the steam heated chest or its equivalent 1g. Thepipes c, d aforesaid are in-communication with the delivery pipe fromthe-fan or exhauster b, so that the air drawn from the chamber iscirculated by the fan or exhauster back again into and through thechamber.

The suction and delivery pipes of the fan b are so arranged andproportioned that the air flowing over the cooling elements 7 travelsatbut a slow rate so 'as'to insure a perfect condensation of the vapors inthe air, while the -jetsat the inletto and exitfrom'the condensing .orcollecting chamber are sufliciently strong to prevent any escape ofvapors from the .cham'be g a. Also, the total area of the air suctionaperture crapertures is so proportioned to that of the air deliveryapertures, as -to insure that there shall be no tendency for air to flowinto the chamber a from without, such as would re sult in a dilutionof'the condensed vapors.

In the arrangement illustrated in Figs. 2 to 7 the vapors are withdrawnfrom the chambers a by means of pipes 72. and are conducted to aseparate condenser (not shown). The gases from said condenser return tothe conduit j in contact with the underside of the heating chest g. Fromj the gases pass by the pipe is to the chamber a-through the aperturesm. The gas is projectedonto the plates 72.- (see Figs. 4,- 5, 6 and 7which direct it onto the fabric. In Fig. 6 the directing plate at theentrance to the chamber a, is shown and in Fig. 7 the directing plate isshown at the exit from said chamber. With the arrangement abovedescribed, the gases returning to the drying chamber are heated beforebeing directed onto the fabric, thus assisting in the drying of thelatter. Having now described my invention what; I claim as new anddesire t0- secure by Letters Patent is i 1. In apparatus for dryingproofed and like fabrics or-materials in combination, a chamber havingan inlet and outletfor the fabric, heating means for drying the fabricin its passage through said chamber, means for passing'the fabr cadjacent to. said heat-.

ing means, means for drawing off the fluid drier through a pipe 71havinga chest-like content of said chamber and for delivering same atthe fabric inlet and outlet, as set forth. 1

V 2. In apparatusrfor drying 'proofed and like fabrics or materials, incombination, a

chamber having an inlet and outlet for the fabric, heating means fordrying the fabric in its passage through said chamber, means for passingthe fabric adjacent to said heat;

mg means, means for condensing the vapor- I ized solvents Within saidchamber, means for drawing off the gaseons content of said I chamber andfor delivering same at the fabric inlet and outlet, as set forth.

3. In apparatus for drying proofed andv like fabrics or materials, incombination, a

chamber having an inlet and outlet for the fabric, heating means fordrying the fabric in its passage through said chamber, means for passingthe fabric through the chamber over said heating means, means forcondensing the solvents vaporized by saidheating means and meanswithdrawing the gaseouscontent of said chamber and delivering it in jetform at. the fabric inlet and outlet,

as set. forth.

In testimony whereof I have signed my name to this specification in thepresence of
